CAN-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 756,573, dated April 5,1904. Application filed December 17, 1903. Serial No. 185,543. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Can- Closures, of which the following is aspecification.

My invention relates to an improvement in cans and can-closures, theobject being to pro vide a can of such construction that the entirecontents may be poured out of it and a closure of such form that adouble seal will be made when the closure is secured in position.

With these objects in view my invention consists in a can having ahorizontal annular rim at the top, the inner edge of which terminates inan outwardly-projecting annular flange, and a top or closure constructedand adapted to fit inside of said outwardly-turned flange and providedwith an open bead which curves outwardly and then inwardly and embracesthe outer surface of the outwardly-projecting flange when the top orclosure is in place.

My invention still further consists in certain novel features ofconstruction and combinations of parts, which will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of the canwith the top or closure in position. Fig. 2 is a vertical sectionthrough the can and top. Fig. 3 is a section through the closure, andFig. 4 is a detail.

A represents an ordinary sheet-metal can. B is the annular top rim,which extends horizontally from the edge of the can-body a suitabledistance inward, it being crimped at its outer edge 1 to embrace bothsurfaces of the outer or upper edge of the can-body to which it issoldered. The inner edge terminates in an upwardly or outwardlyprojecting annular flange 2, which forms the mouth or outlet of the canand which in consequence of extend- 1ng outwardly permits the entirecontents of the can to be emptied. Furthermore, being unsupported at theouter edge it is yielding, thus affording a means of tighter embrace forthe closure which is forced into the mouth.

C is thetop or closure, the main portion of which is cylindrical orslightly tapering, as

found most desirable, and is adapted to be forced or wedged into themouth of the can, the extreme outer edge of flange 2 being adapted toyield slightly to the wedging action of the closure, and thus formatight joint. The extreme outer edge of the closure is preferably curledaround in the form of a circular flange 3, the extreme edge 4 of whichembraces the outer surface of flange 2, it being adapted to fit thelatter snugly, and thus, in connection with the contact of the outer endof flange 2 with the top or closure, form a double seal or a seal at theouter and inner edges practically of the flange 2. At the same time thiscircular flange 3 affords a lateral support for the flange 2, thuscounteracting the tendency of the closure to press it outward, theflange 2 being embraced snugly upon its inner and outer surfaces on theone hand at or near its extreme outer edge and, on the other hand, at ornear its extreme inner edge.

In addition to the advantages mentioned the groove D formed around theouter edge of the closure is nicely adapted for the reception ofparaflin or other medium of a similar nature for insuring a perfectlyair-tight joint, especially when the can is used for fruits, vegetables,and the like.

A closure of this construction gives a good finish to the article, andwhile it makesa tight joint at the same time the top or closure iscapable of being easily removed, when occasion requires it.

A rubber gasket 6 might be placed. beneath the bead 3, as indicated inFig. 4, and when so applied the more force or pressure applied upon thetop or closure the tighter the joint. This method of sealing the can isdesirable for domestic use in canning fruits and vegetables.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1;. The combination with a receptacle having an annular top'rim, theinner edge of which terminates in an upwardly or outwardly projectingannular flange which forms the mouth of the receptacle and between whichflange and the outer edge a groove is formed, of a top or closure themain portion of which is fitted to the flange and the outer edge ofwhich is in the form of a circular flange the extreme edge of which isinturned and embraces the outer surface of the flange some distancebeneath the extreme outer edge of the latter, whereby the flange isembraced both inside and outside.

2. The combination with a receptacle having an annular top rim, theinner edge of which terminates in an upwardly or outwardly projectingannular flange which forms the mouth -of the receptacle and betweenwhich flange and the outer edge a groove is formed, of a top or closurethe main portion of which is fitted to the flange and the outer edge ofwhich is in the form of a circular flange the extreme edge of which isinturned and embraces the outer surface of the flange some distancebeneath the extreme outer edge of the latter, whereby the flange isembraced both inside and outside, and a gasket adapted to be heldbetween the extreme edge of the bead and the bottom of the groove. 7

In testimony whereof I afiix my signature in presence of two witnesses.

HENRY S. BREWINGTON.
